[LLVMdev] Simple NEON optimization
Hi folks, me again, So, I want to implement a simple optimization in a NEON case I've seen these days, most as a matter of exercise, but it also simplifies (just a bit) the code generated. The case is simple: uint32x2_t x, res; res = vceq_u32(x, vcreate_u32(0)); This will generate the following code: ; zero d16 vmov.i32 d16, #0x0 ; load a into d17 movw r0, :lower16:a movt r0, :upper16:a vld1.32 {d17}, [r0] ; compare two registers vceq.i32 d17, d17, d16...
